One of.
Further, the inner surface and the outer surface of above-mentioned built-in covering is both provided with corrosion-inhibiting coating.
Further, above-mentioned built-in covering includes being located at the top covering in 1/3rd region of top and divide positioned at lower part three
Two regions bottom covering, the thickness of the corrosion-inhibiting coating of the top covering is more than the corrosion-inhibiting coating thickness of bottom covering
1.5 again.
Further, above-mentioned built-in covering is the splicing aluminium sheet that thickness is 2mm.
Further, the corrosion-inhibiting coating of above-mentioned top covering is that thickness is 50 μm of F-C paint coating, the bottom covering
Corrosion-inhibiting coating be that thickness is 30 μm of F-C paint coating.
More preferably, above-mentioned steel construction tower body is the steel structure support by ball blast or blasting treatment.
Further, above-mentioned steel construction tower body includes the taper tower body positioned at bottom and the cylindricality tower body positioned at top.
Further, in 20m region of the cylindricality tower body from top down, the surface of steel structure support is provided with thickness
Spend the cold spray zinc undercoating for 120 μm and F-C paint external coating that thickness is 50 μm；In other regions of the cylindricality tower body, steel
The surface of structure stand sets the F-C paint coating that thickness is 85 μm.
Further, the outside of above-mentioned cylindricality tower body is provided with multiple reinforcing rings.
The beneficial effects of the present invention are：
(1) chimney is by being arranged on the inside of steel construction tower body by the present invention, using hot-air in tower by plume rise, makes
The higher that flue gas floats is farther, is more conducive to environmental protection, while simplifies system, has saved occupation of land.And by steel construction tower body
Covering built in the setting of inside, can make flue gas and steel construction tower body completely isolated, prevent sulfur-containing smoke gas to steel construction tower body
Contact corrosion.
(2) steel construction, which reaches indirect cool tower, has the advantages that good low cost, anti-seismic performance, short construction period, environmental protection are prominent, and
All steel and aluminium can recycle after End Of Service, and economic and environment-friendly advantage protrudes.
(3) present invention contacts the probability of flue gas and the power of corresponding corrosive environment according to indirect cool tower different parts, fits
Different anti-corrosion measures has been formulated to answering property, has balanced anti-corrosion effect and using effect.
